Being in a routine of not having sex with your SO can be difficult to break. Libido is a circle in my opinion. When you know you can’t have sex your mind can lower the desire. With lowered desire, you have less sex. Almost like a snowball effect.
Do you still masterbate? Did you while dating? Did you two fool around just not have sex? If your libido was lower even heading into the marriage then it is not just the wedding date.
Do you want to want to have sex? Or, are you perfectly content not having sex? What about your spouse? If you both want to want it you can work on more sexual connection. There are sex therapists of course, but I assume there are self help books that have exercises for married couples to get more sexually connected.
Who and why did you decide to cool it?
Most people I know in long term relationships have less desire for sex when they are exhausted from work or from kids or preoccupied with a lot of stress. It’s getting older and having more responsibilities that usually makes it harder to fit sex in the day. Then it also becomes routine. I never hear any of my friends saying right after they got married their libido drastically changed. I do have friends who complain they never had an irresistible sexual connection with their spouse before or after getting married. Are you happy about marrying him? Any doubts about your relationship with him?
If I were you I would try fake it till I make it for a few weeks. I don’t mean fake an orgasm I mean doing something until it becomes something you want to do. Purposely have sex 3 or 4 times a week and hope that gets things going with a new routine and rekindles sexual desire. Obviously, you should not do it if you will actually feel violated in some way, but it sounds to me that you want to be excited about sex with your husband and so I assume that is not an issue.
